Hao AI Lab's FastVideo makes HunyuanVideo 3x faster with no extra training
Hao AI Lab released FastVideo, a method that makes HunyuanVideo (HY-Video) three times faster with no additional training, using a technique called Sliding Tile Attention that outperforms even flash attention for this workload. Faster inference makes open-source video models far more practical, and it supports HY-Video LoRAs for fine-tuned applications.
